Hello, I was booting rc4-mm3. With rc5-mm1 I am hanging early... Mel I don'tknow if this is related to your code but I will soon know. (I don't getyour debug info in early console.) I was working on patches for the reserve based memory hot add path insrat.c (the initial error is fixed by Mels patches but there is more todo) and was just moving to rc5-mm1 to sync up and then more trouble.This is with reserve based hot-add not enabled at the command line.
